Based on the social structure of free-living mandarin voles (Lasiopodomys mandarinus), high paternal investment might be expected for this species. This prediction was tested under laboratory conditions. We observed 10 pairs rearing their first litter. All pairs exhibited permanent nest cohabitation. Females never prevented males from entering the natal nest. Males exhibited all the patterns of direct care of young except nursing: huddling over, brooding with kyphosis, grooming, manipulating, and retrieving young. There were no sex differences in total time spent in the nest or in time spent alone. Females spent more time grooming pups than did males. There was no sex difference in nest-building activity. The frequency of bringing food or nest material into the nest, as well as in digging time, was significantly greater for males than for females. In L. mandarinus the biparental rearing system with a high level of direct paternal care and some division of labour between the parents seems to be associated with the subterranean mode of life. This pattern of parental care can be predicted for other specialized fossorial voles.

Positive Effect

A male-removal experiment was performed to determine if the value of male parental care depended on the timing of the help. In the experiment male parent was removed before the carcass was prepared for breeding, after partial carcass preparation, after complete carcass preparation, before direct care for the larvae and males were allowed to disperse naturally after caring for the larvae. It was found that where the male provided complete pre-hatching care or both preand post-hatching care offspring were larger and in better condition. Mass of offspring at eclosion was affected by male removal (F3,1266 = 5.087, p = 0.002) though size of offspring was not affected by the treatment group. Complete prehatching care had a positive effect on development compared to limited care (F3, 1267 = 8.501, p < 0.000) but this effect disappeared if males remained after the larvae hatched. Larval survivorship did not vary among treatments (F3,122 = 0.531, p = 0.662).

Food Caching

Male Peromyscus leucopus are known to exhibit well-developed paternal behavior in confined cages, but electrophoresis indicates promiscuity in this species. One explanation for this paradox is that the documented paternal behavioral patterns are laboratory artifacts. We made nocturnal observations of parental behavior in 14 families of P. leucopus in large enclosures and observed no paternal care. Males rarely entered the natal nest and when they did, remained in the nest for less than 2 min. Thus, we consider direct paternal care such as licking, retrieving, and huddling unlikely. We also failed to observe any indirect paternal investment such as nest building or food caching. The female in each of five pairs was very aggressive towards the male, continuously chasing him throughout most of the observation periods. Another three females actively prevented their mates from entering the natal nest. Paternal care probably does not contribute to the growth and survivorship of the young under natural conditions.

Abstract. Factorial survey experiments are increasingly used in the social sciences to investigate behavioral intentions. The measurement of self-reported behavioral intentions with factorial survey experiments frequently assumes that the determinants of intended behavior affect actual behavior in a similar way. We critically investigate this fundamental assumption using the misdirected email technique. Student participants of a survey were randomly assigned to a field experiment or a survey experiment. The email informs the recipient about the reception of a scholarship with varying stakes (full-time vs. book) and recipient’s names (German vs. Arabic). In the survey experiment, respondents saw an image of the same email. This validation design ensured a high level of correspondence between units, settings, and treatments across both studies. Results reveal that while the frequencies of self-reported intentions and actual behavior deviate, treatments show similar relative effects. Hence, although further research on this topic is needed, this study suggests that determinants of behavior might be inferred from behavioral intentions measured with survey experiments.

The following research methods were used to achieve the purpose of intelligence: descriptive (content content, including various examples), comparative (content presentation options) and typological (types, trends of native advertising, in particular, cross-media as an opportunity to submit content in different formats (video, audio, photos, text, infographics, etc.)), content analysis method using Internet services (using Popsters service). And the native code for analytics was the page of the journalism department of Zaporizhzhya National University on the social network Facebook. After all, the brand of the journalism department of Zaporozhye National University in 2019 celebrates its 15th anniversary. The brand vector is its value component and professional training with balanced distribution of theoretical and practical blocks (seven practices), student-centered (democratic interaction and high-level teacher-student dialogue) and integration into Ukrainian and world educational process (participation in grant programs).</em></p></div><p><em>And advertising on social networks is also a kind of native content, which does not appear in special blocks, and is organically inscribed on one page or another and unobtrusively offers, just remembering the product as if «to the word».

This chapter discusses property law. It considers the idea that property had a “nominalist” ontology, and it was in danger of “disintegration” as a working legal category for that very reason. Nominalism about property has had a significant impact in U.S. case law. The concern here, however, is whether it is a helpful stance to take as a theorist of property. The chapter argues that it is not. There are indeed “high” level abstractions about property which one cannot plausibly do without if one is to understand property rights and property law doctrine. Moreover, the “bundle of rights” (BOR) challenge does not assist one in making sense of these abstractions. The chapter then looks at the conceptual failure of BOR and the New Private Law as it relates to property. BOR is generally regarded as being underpinned by what might be called the Hohfeld-Honoré synthesis. The synthesis rests upon a fairly serious mistake, which is that while the Hohfeldian examination of jural norms is analytic if it is anything, Honor’s elaboration of the incidents making up ownership is anything but—it is functional. This means that Honoré describes the situation of the owner not principally in terms of his Hohfeldian powers, duties, and rights vis-à-vis others, but in terms of the social or economic advantages that an owner has by virtue of his position, and the terms and limitations of those advantages.

Integration Analysis

Given the high level of global mobility, pandemics are likely to be more frequent, and with potentially devastating consequences for our way of life. With COVID-19, Australia is in relatively better shape than most other countries and is generally regarded as having managed the pandemic well. That said, we believe there is a critical need to start the process of learning from this pandemic to improve the quantitative information and related advice provided to policy makers. A dispassionate assessment of Australia’s health and economic response to the COVID-19 pandemic reveals some important inadequacies in the data, statistical analysis and interpretation used to guide Australia’s preparations and actions. For example, one key shortcoming has been the lack of data to obtain an early understanding of the extent of asymptomatic and mildly symptomatic cases or the differences across age groups, occupations or ethnic groups. Minimising the combined health, social and economic impacts of a novel virus depends critically on ongoing acquisition, integration, analysis, interpretation and presentation of a variety of data streams to inform the development, execution and monitoring of appropriate strategies. The article captures the essential quantitative components of such an approach for each of the four basic phases, from initial detection to post-pandemic. It also outlines the critical steps in each stage to enable policy makers to deal more efficiently and effectively with future such events, thus enhancing both the social and the economic welfare of its people. Although written in an Australian context, we believe most elements would apply to other countries as well.

Abstract The present paper is concerned with the lecture hall as the natural home of lecturing. We will focus on constructed, designed and equipped space as a material and communicative manifestation of science which fundamentally contributes to the multimodal practice of lecturing. Taking an interactionist point of view, we start off with introducing our concept of architecture-for-interaction which aims at spatial built-in features as a resource for social interaction, namely for situational anchoring among those present. In a second step, we identify key architectural elements of the lecture hall as material sediments of communicative problems connected with the social practice of lecturing. In doing so, we will also give a high-level overview of the historical development of the lecture hall (and its precursors) since the Middle Ages and the Early Modern Age. Turning to current data from lecturing in times of the pandemic, we will then deal with so called „ghost lectures“ behind closed doors. This current development brings out a refiguration process due to which the lecture hall undergoes a change from the classical auditorium with copresent participants to a multi-media hub allowing for tele-present participants.

The purpose of this research is to study the need for the students' communication activity component at the Pharmaceutical faculty of VSMU. Dual feature of the levels indicators dynamics in the need for communication is revealed. On the one hand, there is a tendency to reduce the average level in the need for communication and to increase its high level at the expense of girls. On the other hand, there is a fairly significant increase in the average level in the need for communication among young men against the background of an obvious predominance of the average level in the need for communication among the students of the entire sampling. The study allows us to state obvious influence of the informational educational environment at VSMU on the personal growth of students at the Pharmaceutical faculty, on the formation of their communicative competence as the most important component of the professional competence of future pharmacists. The results of the study can be used in the educational process of VSMU, in the activities of the social and pedagogical and psychological service, in the work of educators in academic groups and for tutors.

Nipponites, a Late Cretaceous nostoceratid ammonite, shows a peculiar meandering shell growth in the middle-late stage. Assuming neutral buoyancy, and a constant aperture angle relative to the sea bottom, meandering growth of this ammonite was modeled by computer simulation. In this model, the meandering shell growth is controlled by regulation of life orientation. The remarkable similarity in the coiling modes and rib obliquity patterns between the computer-simulated and actual specimens strongly suggests a free living mode of life in Nipponites with an approximately neutral buoyancy. The simulation also suggests that morphological saltation from a simple helicoid form like Eubostrychoceras japonicum to a meandering shell form like Nipponites occurred abruptly without any intermediate form by minor change of the upper and lower limits of growth direction.
